Application led April 10, 1923.

The object of this invention is to simplify and improve the gearing andthe manner of mounting the same upon the tvop of the tub, to the endthat the structure will not only be durable, but will be inexpensive tomanufacture, as more fully hereinafter set forth.

1n the drawing- Fig. 1'is a perspective view of the top portion of anice-cream freezer showing my invention applied thereto;

Fig. 2 is a similar view with the gearing removed;

Figs. 3, i and 5 are views of details hereinafter described.

Referring to the annexed drawing by reference characters, 10 designatesthe gearing-carrying bar which, as usual, is adapted to extend acrossthe top of the tub and be removably attached thereto. This bar consistsof a single sheet of steel having its longitudinal edges bent downwardlyto form flanges 11 extending the full length of the bar. Then this baris in place on the tub, the flat under face of the main part of the barrests solid against the upper edge of the tub and the depending flanges11 fit down into notches 12 formed in the upper edge of the tub, thusgiving the gearingcarrying member a strong solid support on the tub andat the same time permitting this member to be constructed of light sheetsteel.

At one end of the bridge-member, there is affixed to the outer side ofthe tub a metal plate 13 whose upper edge extends above the rim of thetub and is provided with a slot 111 through which extends a tongue 15formed integral on the top plate of the bridge member, this tongue beingcurved upwardly so as to interlock with the ear 13 when the tongue ispassed through the slot 14 when the bridge-member is swung down on thetop of the tub. At the opposite side of the tub, a similar plate or ear18 is attached to the tub, and adapted to engage in the slot 111` ofthis latter ear is the locking end of a lock-lever 16 pivotally mountedon the top face of the bridge-member. The top plate of the bridge-memberis provided with a transverse slot 17 up through which the reduced upperend of the ear 13 extends, so as to bring the slot 11i slightly abovethe upper face of the bridge-member, so that said slot will lie inposition to receive the outer end of the locking-lever. By thus SerialNo. 631,151.

making the two upstanding ears exactly alike, it will'be observed thatt-he bridge-` member is thereby made reversible, end-forend, so that inreplacing the gearing on the tub it will not be necessary to botherabout selecting the proper ear for engagement with the locking-tonguethis facilitates considerably the replacing of the gearing on the tub.

The freezer-can and dasher arrangement are constructed as usual. The cantop 18 is provided with a cog-gear 19 and an upstanding journal 2O whichengages a hole in the top plate of the bridge, and the dasher 21 isprovided with a squared shank 22 which extends up through a hole in thetop of the cover and engages in a square hole formed in a bracket 23.The gear 19 is driven from a driving-gear 24C aflixed to the squaredpart of a short shaft 25 which has it upper end journaled in a hole inthe bridge-member and is provided with a handcrank 26. The lower end ofthe shaft is journaled in a hole formed in a plate 27 which is rivetedto the under side of the bridge-plate at 28. It will thus be seen thatthe rotation of the crank-handle in a horizontal direction will drivethe cream-can in one direction, while the dasher is held stationary bythe squared shank 22 and the bracket 23.

A feature of importance lies in the manner of supporting the shaft 25.The lower end of the shaft extends, as stated, through a hole in thesupporting-plate 27, and the shaft is prevented from dropping downthrough this hole by the squared portion which engages thedriving-wheel. The supporting-plate 27 is the full width of the channelformed by the depending flanges 11 and is bent transversely at 29 and 30to form an upwardly-extending wall 31 and an outwardly-extendingsecuring-flange 32 which lies against the under face of the sheet-metalbridge-plate. In this way, the driving-gear is housed, a substantialsupport is provided for the driving-shaft 35 and the supporting-platefor this shaft is utilized to brace the sheet-metal bridgemember.

It will be observed that the locking-end of the lever 16 is a broad flatplate approximately equal in width to the length of the slot 14, thusproviding a broad substantial engagement with the upstanding ear on thebucket, -to thereby hold the bridge squarely down on the tub and preventtwisting and rocking of the thin sheet steel bridge.

TWhat I elaiin is ln an ice-cream Afreezer embodying a Wooden tub havingtwo pairs Oi' separated narrow notches formed in its riin atdialnetrically opposite sides, upstanding slotted ears affixed to thetub between saidnotehes, a brido'e-lnen'iber consisting of a piece ofsheet inetal having its longitudinal edges bent down to forni flanges,said flanges itting down in said notches and extending through ythe fullthickness of the tub-Wall to permit the body portion of the bridge-.Ineinber to rest flat against the riin ot the tub7 gearing carried bysaid bridge-niember, and `astening means carried by the bridge-membersolidly against the tub-rim 4and the/flanges down in said notches.

In testimony whereof I hereunto aflix my signature. Y

JAMES EDVARD MINSON.
